Solar Collectors - SolEnergi


Our solar collectors are designed to capture solar energy and heat domestic water, and are supplied as a package with differential solar controller and pump station. Various options such as on roof or in roof for fitting are available. The SolEnergi provides a complete system with Ecoline Solar cylinders.

OSO SolEnergi solar collectors are designed to maximize the available solar energy capture and transfer to domestic hot water. An ultrasonically welded single piece copper absorber plate with a highly selective finish absorbs energy & prevents it bouncing back into the atmosphere. Once absorbed, the heat is transported in a glycol mix to be transferred to the domestic hot water.


Heat loss from the collector into the roof is prevented with 40mm rock wool insulation. The collectors have a robust structure with aluminium casing and 3.2mm low iron tempered glass.

SolEnergi collectors are 2.2m2 aperture area but have a low 40kg weight. They are Solar Keymark approved and guaranteed for 10 years.

A differential solar controller with choice of operation modes encourages the maximum possible solar input and interacts with the boiler to reduce fossil fuel usage.
